Application filed September 11, 1905. Serial No. 277,909.

/ erally beyond the" adjacent parts of the frame and are adapted'to' be adjusted to act in different positions whereby otherwise inaccessib le rivets may be reached, and the shifting and moving of the work being riveted is reduced to a minimum. f, In the riveting of the parts of structuraliron work it is" frequently necessary to handle fiang'edmaterial, such as angle-bars and the like,'bent.into L or U shaped or other irregularforms, where one part of the, strucber.

ture extends at an angle with respect to the other part. In the use of my machine on work of this character the riveting of one of the angular portions or limbs of the work is efiected.

by setting the riveting-jaws in one position and shifting the work horizontally in a direction lengthwise of the member being riveted, with the result that the rivets will be set at intervals in the length of said mem- As the adjoining angularly-related limb of the work is reached instead of twisting the work around to present this adjoining limb to the action of the riveting-jaws the latter are turned transversely, and the work is maintained in its former position, but is moved horizontally in a direction lengthwise of the second limb being riveted. If the work' comprises a third angularly-related limb, such as a U-shaped structure, the last limb is riveted by setting the riveting-jaws to a third lateral position and then again shifting the work horizontally in the direc tion of the length of the third limb of the work. By the projection laterally of the riveting-tools beyond the adjacent portion of the frame there will be no interference with or obstruction offered to the depending flan es on the material being riveted, which won d be the case if the riveting-tools were situated within the limits of the frame. Further, it is possible by means of the laterallyprojecting rivetin -jaws to set rivets in the corners of the wor and in similar otherwise inaccessible locations.

In the accompanying drawings, Figure 1 is a side elevation of my improved machine. Fig. 2 is a horizontal sectional plan view on the line a a of the preceding figure. Fig. 3 is a vertical longitudinal sectional elevation on the line b b of Fig. 2. Fig. 4 is a vertical transverse section on the line 0 c of Fig. 3.

Referring tothe drawings, 1 represents the main frame, embodying a horizontal supporting-bed 2 and an overhanging arm 3, the

supporting-bed giving support to a lower riveting-j aw and the overhanging arm sustainjing an upper riveting-j aw movable relatively to the lower jaw to and from the same.

The lower jaw comprises a vertical cylindrical stem 4 and a horizontal projecting riv I eting-j aw proper, 4, on the upper end of the stem, which jaw proper is adapted to act on one end of the rivet and is formed with flat parallel sides a. loosely in a vertical socket in a post 6, rising from the bed 2, and in such manner that while the stem may turn in the socket to pre sent its riveting-j aw in diflerent positions it is confined therein against endwise movement.

The upper 'aw is of a form similar to that described em odying a vertical cylindrical stem 5 and a horizontal projecting rivetingjaw proper, 5, on its lower end, which 'aw The stem is mounted proper is adapted to act on the other en of circling and fixed to the stem by means of a fastenin 'pin 8", the arrangement being such that whi e the stem maybe turned in the head to present its riveting-j aw in different positions it is caused to move vertically with the head, so as to cooperate with the lower riveting-jaw in heading the opposite end of the rivet.

By turning the stems of the two jaws in their sockets the riveting-jaws proper, as before stated, may be swung around transversely of their riveting movements and presented in different p ositions, and in whatever position adjusted they will be subject to the action of the actuating mechanism to be described later. In order that the jaws may be conveniently adjusted and moved in unison, I fix to the upper jaw proper a U-shaped frame 9, the sides 9 of which are parallel and slidingly embrace the flat parallel sides of the lower riveting-jaw, so that while the upper 'aw may be moved vertically relatively to the lower jaw, with the U-shaped frame sliding alon the sides of the lower jaw, the latter will e caused to be turned when the upper jaw is turned for adjustment. The U-shaped frame therefore forms, in effect, an operative connection between the two riveting-jaws, compelling them to be swung or adjusted in unison while permitting of a movement of one jaw in relation to the other in performing the riveting action.

The swinging movement or adjustment of the jaws is effected by means of an operating and locking lever 10, pivoted on a horizontal axis near its inner end, as at 10 between ears 8*, projecting forwardly from the collar 8, the lever being provided with a depending nose 10*, adapted when it is swung downward to enter either of a series of notches 11, 12, and 13, formed in a rib 14, projecting forwardly from the sliding head 7, and in this manner serving to lock the jaws in their adjusted position.

In the present instance I have shown three predetermined positions to which the riveting-j aws maybe adj usted-a central position, as shown in Fig. 1, and two side positions oppositely disposed, as represented by the dotted lines in Fig. 2which several positions are determined and controlled by the engagement of the locking lever in the several notches. It is manifest, however, that the jaws may be ad'usted and locked in other positions beyon the range of those illustrated or intermediate of the same.

In the use of my apparatus, if it is desired to turn the riveting-jaws from their medial forward position of Fig. 1 to the right or left, the adjusting-lever is raised and its nose disengaged from the central notch and is then swung to the side, thereby turnin the stem of the upper jaw in its socket an swinging the riveting-j aw proper around, which action will, through the medium of the U-shaped connecting-frame 9, cause the lower riveting jaw to be correspondingly turned. The lever is then lowered and its nose en aged in one of the side locking-notches, in w ich position the parts will be locked with the two riveting-jaws proper subject to the action of the actuating mechanism in their adjusted position.

Any appropriate means and mechanism may be employed for moving the head 7 vertically to effect the operation of the upper riveting-j aw but I prefer to adopt the construction shown more particularly in Fig. 1, where it will be seen that the head is fixed to a vertical cylindrical rod 15, sliding and guided at its lower portion in a guidingsocket in the post 6 and extending in rear of the stems of the riveting-jaws. The upper end of the rod 15 is fixed to the lower end of a plunger 16, mounted to slide vertically in the overhanging arm 3 of the main frame, which plunger is operated, by means of a piston 17, in a cylinder 18, sustained by the frame. The rod 19 of the piston is connected with one arm of an elbow-lever 20, which lever is mounted between the upper ends of standards 21, rising-from the overhanging arm 3 of the main frame, the other arm of the elbow- .lever being connected with the plunger 16 by means of a connecting-rod 22a Having thus. described my invention, what I claim is 1. In a riveting-machine, the combination of a frame, riveting-jaws movable one with relation to the other to perform the riveting operation, said jaws projecting transversely beyond the adjacent portions of the frame, jaw-actuating mechanism, and means for adjusting said jaws in a direction transversely of their riveting movement.

2. In a riveting-machine the combination of a frame, riveting-jaws mounted therein and movable one with relation to the other to perform the riveting operation, said jaws extending laterally beyond the adjacent portions of the frame, means acting on one of said jaws for adjusting it in a direction transversely of the riveting movement, and an operative connection between said jaw and the other one; whereby the latter is caused to be adjusted in unison.

3. In a riveting-machine, the combination with a frame, of rivetin jaws sustained thereby and com rising eac a stem mounted loosely in the rame, and a riveting-jaw proper extending laterally beyond the frame, means for moving one of the jaws with rela tion to the other in the direction of the axis of the stems, and means for adjusting said jaws around the axis of the stems.

4. In a riveting-machine, the combination of the frame, two riveting-jaws, one movable to and from the other to perform the riveting operation, said jaws being movable also transversely of the riveting movement, one of said jaws having flat sides, a frame carried by the other jaw and loosely embracing said flat sides, and means for moving one of the jaws transversely; whereby the other jaw will be moved in unison.

5. In a riveting-machine, the combination with a frame, of rivetin -jaws mounted therein and extending radia ly from a center and beyond the ad acent portions of the frame, actuating mechanism therefor, and means for adjusting said jaws around said center, subject to the action of the actuating mechanism.

6. In a riveting-machine the combination of a frame, riveting-jaws projecting horizontally beyond the adjacent portions of the frame and movable around vertical alining axes, means for moving one jaw to and from the other to perform the riveting operation, and means for adjusting said jaws to difierent positions around their vertical axes.

7. In a riveting-machine, the combination of a frame, an upper vertical stem mounted therein and movable around a vertical axis, a horizontal riveting-jaw fixed to and proj ecting laterally from said stern, a lower vertical stem mounted in the frame and movable around a vertical axis coincident with that of the upper stem, a horizontal rivetingjaw fixed to and projecting laterally from said lower stem and adapted to cooperate with the jaw on the upper stem, means for moving one of the jaws to and from the other to perform the riveting operation, an adjusting-handle fixed to one of said stems for turning it around its axis, operative connections between said stems; whereby the adjusting movement of one stem will be imparted to the other, and means for interlocking the handle with the frame of the machine to hold the stems in their adjusted position.

8. In a riveting-machine, the combination of a frame, a vertically-movable head 7 mounted therein, an actuating-plunger operatively connected with said head, a stem carried by the head and movable therein around a vertical axis, a laterally-projecting riveting-jaw on the lower end of the stem, a second stem mounted in the frame of the machine below the first and movable around an axis coincident with that of the first, a riveting-j aw projecting laterally from the upper end of the second stem, an adjusting-handle fixed to the upper end of the first-named stem and adapted to adjust said stem around its axis, said handle being formed to be interlocked with the head 7 to hold the stem in its different positions, and operative connections between the adjacent ends of the stems; whereby the adjusting movement of the firstnamed stem will be imparted to the other.

In testimony whereof I hereunto set my hand, this 22d day of August, 1905, in the presence of two attesting witnesses.
